How Do I?

What do the abbreviations DOI or PMID mean in my citation?

Answer

DOI ("Digital Object Identifier") and PMID ("PubMed IDentifier") are numbers assigned to identify an article uniquely. DOIs are created by the International DOI federation, and PMIDs are created by the Pubmed database, run by the US National Library of Medicine and the National Institutes of Health. If you see a DOI or a PMID in a citation, you can type that information into the appropriate fields in the library's "Find an article" box to search for the full text.
